To a/ZZ whom it may concern/.- n

Be it known that l, NIOOLAUS HEID, a subv ject of the Emperor of Germany, residing at Stockerau, near Vienna, Vin the Province of Lower Austria',in the Empire of Austria-Hungary, have invented certain new and 4useful Improvements in Grain-Separatore; and I do hereby declare the following to beafull,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to thel accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

For the separation of both the lenticular and the globular seeds of weeds from grain there has hitherto been employed either a sorting-cylinder having only large recesses or cells for the reception of such seeds or having large cells inthe upper part of the cylinder and smaller cells in the lower part, or two cylinders are employed, of which the one has large cells and the other -smaller cells. The cylinder with large cells has the disadvantage that many good and useful seeds of cereals or grain are also taken up by the cells, thus causing a loss in the yield. The cylinder with two kinds of cells has in addition the disadvantage of a more limit-ed production, and the use of two cylinders having different-sized cells causes, in addition to the increased cost, double the expenditure of time for effecting the purification of the grain from the seeds of weeds, as the grain has to be fed in twice.

The present invention relates to the coustruction of a separating or sorting plate, the cells of which are formed with stepped walls, by which means the above-described disadvantages are obviated.

The accompanying drawings show, by way of example, some forms of separating or sorting plates constructed according to my said invention.'

Figure 1 is a plan view of a portion of a grain-separating plate before being bent for use in the construction of the separatingcylinder. Figsp2 and 3 are sections taken, respectively, on lines 0c .fr and y y of Fig. l. Figs. 4 to 7 are sections of portions of such plates, illustrating a modification in conguration or arrangement of the enlarged portion of the recesses or pockets relatively to the smaller portion thereof. Fig. Sis a vertical longitudinal section of a grain-separator embodying my invention. Fig. 9 is a cross-section of the separating-cylinder. Fig. lOlis a fragmentary longitudinal section, and Figli a similar cross-section, ofsaid separating-cylinder, the latter havingA pockets Such as shown to an enlarged scale in said Figs. 9 and l0 and in Figs. l, 2, and 3.'

The cells a, which in the form shown in the drawings -may'be produced either by a cutting or stamping operation or by any suitable known means, have their walls formed with a step or offset b, extending right around, Figs. 1, 3, 6, and 7, or Iiattening at one side, so as to be on a level with the wall-surface of the cell, Fig. 5, in such a manner that at this point the upper part of the cell will terminate with the lower part of the same .in the shape of a perpendicular edge. Owing to this step or offset the upper part of the cell will have a greater width than the hemispherical lower part of the cell. By this means the small globular seeds of weeds are taken up and retained in the smaller part of the cells, while the larger upper part serves vto take up the larger lenticular-shaped seeds,

which could not be retained by cells of the usual diameter for retaining the small globular seeds. Small, but good, cereal seeds can only enter the lenlarged part of the cells, so that on the rotation of the cylinder they will fall out of the cells again before they have been raised to the height at which the channel is situated for 'receiving the seeds of weeds, as shown at g, Fig. 1l. The lenticular seeds of weeds are, on the other hand, sufficiently retained in the enlarged part of the cells to cause them to be carried up to above the said discharge-channel. The small depth of the part of the cell above the offset prevents these larger seeds from becoming lodged too firmly in the cells, so that axes inclined .to the surface of the plate their axes may also be made perpendicular thereto, as shown at Figs. 5 and 7. Fig. 7, as well as IOO Fig. 6, further shows that the plate may also be perforated in the direction ot the axes of the cells.

In Fig. 8 I have shown a grain-separator the separating-cylinder c ot which is constructed of plates having pockets such as shown in Figs. l, 2, and 3. The cylinder is mounted on and revolves with a shaft s, that carries a gear-wheel w, meshing with a pinion p on a stud or short shaft s', that carries the belt-pulleyp', belted to any suitable prime motor. The shafts is mounted and revolves in bearings on standards s2 at an angle to the horizontal, the grain being fed to the cylinder from a feed-hopper h, the spoilt of which projects through the open cylinderhead at its higher or elevated end to deliver the grain to said cylinder at a point below the seed-collector or trough t, which is suspended from hangers loosely mounted on shaft s, said hangers having bearings for a screw-ccnveyer S, carrying at its lower or outer end a pinion p2 in gear with a toothed wheel 102, fast 0n shaft s. At its lower or outer end the cylinder o is provided with numerous large discharge-openings c, through which the separated grain passes into the discharge-spout d, while the cockle and other undesirable smaller seed is forwarded by the conveyer S through the lower head of the separator-@yhnder to the discharge-spout (ZC I claiml. A grain-separatingcylinderconstrueted of plates having seed-pockets, each pocket being of different cross sectional areas and having an offset between theinner portion of greater area and the other portion, for the purpose set forth.

2. A grain-separating cylinderconstructed of plates having seed-pockets, each pocket being of diierent cross-sectional areas, and having an oset between theouter portion of least area and the inner portion, the latter having its wall inclined to the surface of the plate in the direction of rotation of the cylinder, for the purpose set forth.

Agrain-separatingcylinder,constructed of plates having pockets, each pocket being of diierent cross sectional areas, the inner circular portion thereof being or' greater area and eccentric lo lhe outer heinispherical portion, for the purpose set forth.

4. Agrain-separatingcylinder,constructed of plates having pockets, each pocket being of diiferent cross-sectional areas, and having the inner circular portion of greater area and eccentric to the outer hemispherical portion, and an offset between said circular and hemispherical portions, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed my name in pres- YosEF RUBARCH, ALvEsTo S. HoGUE.
